Brief about the initial process sequence while the system boots up. Ans. While booting, special process called the 'swapper' or 'scheduler' is created with Process- ID 0. The swapper manages memory allocation for processes and influences CPU allocation. The swapper inturn creates 3 children: 1. the process dispatcher, 2. vhand and 3. dbflush with IDs 1,2 and 3 respectively. This is done by executing the file '/etc/init'. Process dispatcher gives birth to the shell. Unix keeps track of all the processes in an internal data structure called the Process Table (listing command is ps -el).
